I asked here:
forum.cncdrive.com • View topic - AXBB power supply question

Stepper motors need their own power supply, that connects to the drives. Depending on the drives, it's usually 48V-60V, but can be 24V-36V for smaller motors.

DMM DYN4 drives are AC drives, and do not need a power supply.
Clearpath and DMM DYN2 are DC drives, and do need a power supply.
Totally clear. Thank you.
